摘要打击精确度在现代战争中占据着越来越重要的地位,精确制导武器的需求量不断增加,为了能够快速的提高精确制导弹药的装备量,将以往的笨弹加以改造是最快捷有效的方法。本课题以120mm迫弹的弹道修正技术为应用背景,主要研究弹道修正弹电动舵机的设计,为二文弹道修正弹的深入发展提供思路。
本毕业论文分析了国内外弹道修正弹的现状以及电动舵机的发展现状,提出一种滚珠丝杠与空间连杆结合的电动舵机结构。本文对电动舵机的总体方案进行设计,对各部分的运动参数进行了理论计算,计算出舵机整体传动比。根据理论计算结果以及任务要求,确定了结构的主要参数。之后通过参数化建模的方法,对舵机中的杆长进行了优化,使得舵机的性能达到技术要求。然后选择了电机与滚珠丝杠,设计了环轴,RSSR空间连杆,舵翼片等部件的具体结构。在文章的最后建立了电动舵机的虚拟样机并对性能参数进行了检测。20547

Abstract
Attack precision in modern warfare occupy an increasingly important position, precision-guided weapons, increasing demand, in order to quickly raise the amount of precision-guided munitions and equipment, the past is the only way to transform stupid bomb. The topics to 120mm Mortar trajectory correction technique for the application background, the main research trajectory correction projectile electric servo design for the further development of two-dimensional Trajectory Correction to provide ideas.
This paper analyzes the current situation and development status of Trajectory Correction electric steering gear, power steering proposed structure of a ball screw and rod combination space. The overall program is designed to power steering in this article. Motion parameters of each part of the theoretical calculations to estimate the overall steering ratio. According to the results of theoretical calculations and mission requirements, the main parameters of the structure is intended. Then through parametric modeling approach, the four steering rod length is optimized so that the servo performance meet the technical requirements. Then the motor and ball screw is selected, the specific structure of the ring axis, RSSR spatial linkage, rudder fins and other components are designed. In the last article of the virtual prototype electric steering and performance parameters are detected.
Keywords : Trajectory Correction Projectiles, electric steering, multi-body dynamics simulation, RSSR.
